. recognized. With a View to provide for this want, and `to facilitate the proper adjustment J of the feed-regulatingdevice, the'reservoirs have heen made of glass or with glass sides,

through which the quantity of v oil contained therein might be seen; but the facility thus afforded for ascertaining whether the lubricator `was feeding properly was very imperfect, `as theaction could only be determined by watchh ing the gradual diminution of the level of the oil inthe reservoir, Vwhich was necessarily te` dious. l. The object of this invention is to provide for `thebetter observation of the operation; and to this end it consists in the provision, belowthe reservoir and the feed-regulating device and the contractedorilice `through which the oil escapes` from the reservoir, of a chamber of such capacity that the oil`or other lubricating material drips through the said chamber, instead of trickling down over the surface of the passage leading from the reservoir and feed- `regulating device to the bearing or other device to be lubricated, suchchamber. having 4openings inA its sides, or being partly constructed of glass, and thereby enabling the dripping of the oil within or through it to be distinctly seen. In ordertoinsure the dripping, instead of the trickling, ofthe oil'or lubricating material from the reservoir through the said chamber, one feature of this invention consists in providing a teat around the orifice, through which the oil or lubricating material passes into the lsaid chamber. l

Similar letters of reference indicate corresponding parts in both -gures f F screwing into this socket.

A is thereservoir, B the feed-tube, and c the adjusting valve or plug for regulating the feed. These are represented of a well-known construction, serving as well as any other to illustrate the application of my invention; but the" reservoir and feed-regulating device may be of any other known or suitable construction whereby a contracted orice is provided at the bottomof the reservoir for the escape of the I oil or other lubricating'inaterial.

F H I is the drip-chamber arranged below the reservoir and feed-regulating device and between the said device and the hollow stem G, which is inserted into the support for the lubricator. This chamber is formed in part of a hollow cylindrical shell of metal, F, which is made in the same piece with or attached to the bottom of the feed-tube B, and in part by a socket, I, provided on the stem G, the shell interior of the said chamber'visible, holes E E of suitable size are provided in the sides of the cylindrical shell F, and to prevent theentrance of dust, while still permitting the interior to be seen, the said shell is lined'with a 'glass tube, H; or small plates of glass may be fitted to the holes E E for 'the same purpose.` At the top/of the said chamber, surrounding the lower orifice of the feed-tube, is the tcat a, on which the oil or lubricating material collects to form the drip.

The operation is as follows: lhe oil or other lubricating material passing the feed-regulaty ing valve or plug C collects in the lower part of the feed-regulating tube until there is a sufficient accumulation at the lower orifice of the said` tube to form apdrip, which drips through the chamber F H I to the `bottom thereof,

whence it passes through the hollow stem G to the place to be lubricated. The dripping taking place frequently can be observed through the openings E Eof the chamber, and the quantity supplied can be so easily determined as to enable the feed-regulating device to be properly adj usted. The delivery of the oil in drips is better insured by the teat a, formed around the lower orifice of the feed-tube, or by what would be equivalent by the making of the interior of the upper part of the chamber or' convex form.

This invention differs from all other lubri.`
